Following ground-breaking marketing limits, children in Chile saw 73% less TV commercials for harmful foods and beverages.


According to a research published in the International Journal of Behavioral Nutrition and Physical Activity, Chilean rules intended to control the marketing of unhealthy foods are successful in shielding kids from the barrage of television commercials (TV ads) promoting these items.n nChildren’s exposure to TV advertisements for regulated foods and beverages (those that exceed legal standards for calories, sugar, salt, or saturated fat) decreased by 73% by 2019 as a result of the nation’s multi-phased laws, which started in 2016. Ads for unhealthy foods decreased 64% overall over this time on TV and 77% during children’s programming. Additionally, research revealed that 67% fewer advertisements for unhealthy foods included child-oriented creative material, such as cartoons, characters, toys, or competitions, which are all forbidden by the country?s laws.

These and other findings from researchers at the University of Chile, Diego Portales University and the University of North Carolina at Chapel Hill underscore both the potential and need for strict rules around marketing to build healthier eating habits.n

The study also highlights the importance of a key policy addition contributing to the regulations’ success: The initial Law of Food Labeling and Advertising in 2016 limited child-directed creative content in any marketing and prohibited companies from placing TV ads for regulated products during programs attracting a child audience. In 2018, Chile extended this prohibition to a full “daytime” ban across all TV from 6 a.m. to 10 p.m. While researchers saw a decline in advertising for unhealthy foods during earlier phases of the law (in 2017 and early 2018), the significantly greater drop following the full daytime ban is noteworthy.n

Key findings

  • Total TV advertising dropped 64% for unhealthy foods and drinks (i.e., those high in calories, sugar, salt and/or saturated fat) from 2016 (pre-regulation) to 2019, after the full 6 a.m. to 10 p.m. ban began.
  • TV advertising for unhealthy products during children’s programming dropped 77% from 2016 to 2019.
  • Children viewed 73% fewer TV ads for regulated products in 2019 compared to 2016.
  • The number of TV ads for unhealthy foods and drinks that used prohibited child-directed content (e.g., cartoon characters, prizes, games) dropped 67% from 2016 to 2019.
  • For all outcomes, impacts were significantly greater after the full 6 a.m. to 10 p.m. daytime advertising ban began in 2018 compared to earlier restrictions during children’s programming only (in 2017 and early 2018).

“Focusing on child-directed ad content and child-directed programming to reduce children’s exposure to unhealthy food advertising does work to an extent, based on what we’ve seen in Chile, but children are simply exposed to much more than this,” said Francesca Dillman Carpentier, Ph.D., W. Horace Carter Distinguished Professor at the UNC Hussman School of Journalism and Media and the study’s first author. “To markedly reduce the amount of unhealthy food promotions children view, we see that it takes a bold move like Chile’s 6 a.m. to 10 p.m. ban to be effective. The number of unhealthy food ads on TV, as well as kids’ exposure to them, was greatly reduced after Chile added the daytime ban on these ads.”n

This study’s findings underscores a weakness of nearly all governmental restrictions on TV advertising for unhealthy foods worldwide: Most focus on very narrow windows of time or programming, leaving children exposed most of the day and night to targeted ads for unhealthy foods and drinks. This study provides evidence that countries could significantly strengthen existing policies by expanding TV restrictions to complete bans. Countries considering introducing policies to regulate food marketing can also learn from the Chilean experience to protect children more effectively from ad exposure.n

Chile enacted marketing controls in 2016 as part of an ambitious, comprehensive policy package aimed at reducing unhealthy foods and banned their sale or promotion in schools.n

This remains one of the most ambitious regulatory frameworks in the world aimed at tackling rising nutrition-related diseases and soaring health care costs, and many policymakers and public health advocates worldwide have been watching to gauge the policy package’s effectiveness.n

Other studies evaluating the combined effects of Chile’s marketing restrictions, warning labels and school ban have yielded similarly promising results:n

  • A study of household grocery purchases found a 24% drop in calories purchased in the first year (during the most lax period of the law’s three-phased nutritional criteria) and a 37% reduction in sodium purchased.
  • children to avoid buying foods with warning labels.
  • Students reduced their sugar, saturated fat and sodium intake in schools?albeit with some evidence of compensation outside of school settings.
  • Marketing restrictions also led to the removal of child-directed marketing strategies from nearly 50% of breakfast cereals to just 15% in the first year of the law.

“The Chilean experience has shown us that rigorous food marketing regulations work to reduce kids’ exposure to TV food advertising,” said co-author Lindsey Smith Taillie, Ph.D., associate professor and associate chair of academics in the Department of Nutrition at UNC-Chapel Hill’s Gillings Global School of Public Health.

“Looking to the future, we need to figure out how to monitor and regulate the digital food marketing environment, as kids increasingly shift their attention to smartphones and other online content.”
